A personal FM transmitter is a low-power FM radio transmitter that transmits a signal from a portable audio device (such as an MP3 player) to a standard FM radio. Most of these transmitters are connected to the headphone jack of the device and then transmit the signal through an FM transmission band frequency, so that it can be picked up by any nearby radio. This allows portable audio devices to use the highest or best sound quality of a home audio system or car stereo without the need for a wired connection. They are often used in cars but the ....etc

Audio Amplifier Circuit



In the first part of lab#1 you will construct a low-power audio amplifier/speaker driver based
on the LM386 IC from National Semiconductor. The audio amplifier will be a selfcontained, battery-operated component. In the second part of the lab you will construct a
microphone circuit using a compact electret condenser microphone cartridge. These circuit
modules are important building blocks of many audio communications systems, and will be
used in our ultrasonic transceiver system. ....etc

Aim:
To provide easily accessible and appropriately structured information about: pioneering European ATM networking platforms (also called testbeds); important research and development activities closely related to these platforms; and significant trial results, being the outcome of such research activities.
To provide a facility for on-line remote monitoring and, to a more limited extent, control of the said ATM networking platforms.
To use the monitoring facility, so as to allow to an enlarged audience to witness selected important ....etc

SCR is abbreviation for Silicon Controlled Rectifier. SCR has three pins anode, cathode and gate as shown in the below figure. It is made up of there PN junction diodes also; it is solid state equivalent of gas filled triode and has around four semi conductor layers. SCR can conduct the current in a single direction or we can say SCR s are unidirectional. The SCR can be triggered only at the gate through the current. SCR will combine the features of rectifier and transistor. They are mainly used in switching applications. They can also be trig ....etc

POWER SUPPLY NOISE REDUCTION USING ACTIVE RESISTORS


Introduction

Continual scaling in integrated circuit technology has made it possible to achieve higher transistor density
in a given die area. Even with the lowering of the power supply voltage for newer process nodes, the
maximum power consumption of high-end microprocessors has been projected to continue to increase for
the foreseeable

Circuit of an automatic switch for audio power amplifier stage is presented here. The circuit uses stereo
preamplifier output to detect the presence of audio to switch the audio power amplifier on only when
audio is present. The circuit thus helps curtail power wastage. IC1 is used as an inverting adder. The
input signals from left and right channels are combined to form a common signal for IC2, which is used
as an open loop comparator. IC3 (NE556) is a dual timer. Its second section, i.e., IC3(b), is configured
as mono ....etc
